Step 2: MP3 Kit
Step 3: VU Meter
Step 4: VU Meter Positive
Step 5: Solder Your Switches Together.
I used a handy little tool from www.CuriousInventor.com, a crimper for this small connector. You don't need this, you could solder or use pliers, but it is so much easier to use.
Step 6: Box
The meter from RadioShack meter included a template to use for drilling the hole. I used a drill press and a bimetal hole saw.
Step 7: Mark the Box for Switches
I was having a problem in some of my past projects lining up all the holes for switches so they would look good.
I covered the box with masking tape, used a square (also form curious inventor) and marked with a pencil. This was the first time I tried this and it worked out really well.
Step 8: Holes for the Boards
Step 9: Power and Stereo
Step 10: Put It Together
I ran one LED for showing power was on, and then moved the two LEDs from the MakeMP3 board off to the outside of the case along the top where you see the LED holders.
